Paprika is a “beautifully designed” program that “offers just about everything a modern home chef could desire.” It lets you enter and organize old recipes, allows one-touch copying of recipes online, and generates meal plans and shopping lists. ($5; Android, iOS, or Kindle)
Big Oven “takes the hassle out of digitizing your recipes.” Just snap a photo of a handwritten recipe, and for 60 cents a pop, Big Oven will convert it to digital text. You also get access to 250,000 communal recipes, searchable by ingredient. (Basic service free; Android, iOS, or Kindle)
Springpad and Google Keep don’t specialize in recipe organization, but these free notepad apps will do the job for cooks who have a relatively limited recipe library. Springpad even generates shopping lists and wine pairings.
